The Siemens 5SY7306-7 is a robust miniature circuit breaker designed to provide reliable overcurrent protection in a variety of applications. Engineered for performance, this 3-pole breaker features a C tripping characteristic, ensuring a quick response to short-circuit conditions and overloads, safeguarding equipment and preventing electrical hazards.
With a rated current of 6A and a supply voltage rating of 400V for AC systems, the 5SY7306-7 is capable of handling a switching capacity current of up to 40kA according to IEC 60947-2 standards, and 15kA in DC applications as per the same standard. This high breaking capacity makes it suitable for industrial and commercial settings where reliable circuit protection is paramount.
The device's compact design, with a width of only 54mm and a depth of 76mm, allows for efficient use of space inside electrical enclosures. The quick assembly system facilitates easy installation, while the ability to mount in any position offers flexibility in system design.
Constructed with safety in mind, the 5SY7306-7 is equipped with touch protection and is both halogen-free and silicon-free, contributing to a safer working environment. It also features a mechanical service life of typically 10,000 switching cycles, ensuring longevity and reducing maintenance needs.
This miniature circuit breaker is a testament to Siemens' commitment to quality, offering a combination of protection, durability, and ease of use that makes it a valuable component in electrical protection systems.
